[vtkusers] python array syntax

[David Doria]

I am trying to rename an array:

input = self.GetPolyDataInput();

oldColors = input.GetPointData().GetArray("RGB colors")
oldColors.SetName("colors")

it says "no attribute SetName"

2) I want to get a tuple from an array:

oldColors = input.GetPointData().GetArray("RGB colors")
a = oldColors.GetValue(0);

it says "no attribute GetValue".

Anyone know the correct syntax for either of these?

Thanks,

David
